WILLIAM MATTHEWS, OF PEAK HILL, NEW SOUTH WALES.

EARTH-SCOO P.

SPECIFICATION forming part of Letters Patent N 0. 687,640, datedNovember 26, 1901. Application filed June 7, 1900. Renewed October 23,1901. Serial No. 79,681. (No model.)

To aZZ whom it may concern:

Be it known that 1, WILLIAM MATTHEWS, a subject of the Queen of GreatBritain and Ireland, and a resident of ,Peak Hill, in the Colony of NewSouth Wales, have invented a new and Improved Earth-Scoop, of which thefollowing is a full, clear, and exact de- 'scription.

The obj ects'of this invention are to provide an earth-scoop, first,which is stronger, more efficient, and simpler of construction than anynow in use; second, in which'the adjustments are more completely underthe control of the driver; third, which obviates any danger of tippingwhile being filled, and, fourth, in

which the load is more simply and effectivelj retained during itstransit.

The invention will be hereinafter particularly described and thendefined in the claims.

To make my invention clear I shall now refer to the accompanyingdrawings.

Figure 1 is a side elevation showing the scoop in position for filling.Fig. .2 is a side elevation showing scoop in position for transit. Fig.3 is a side elevation showing scoop in position ready for tipping; Fig.4 is a plan of scoop. Fig. 5 is a detailsectional view takentransversely through the lever H, showing a manner of connecting thescrew J therewith.

Similar letters of reference indicate the same parts in the difierentfigures.

A is the body of the scoop.

A A are shields attached to the sides of the scoop to throw the dirt"from in front of the wheel.

B is a frame connecting the trunnions C C on which the scoop revolvesand which carry the rear wheels with swivel guide-wheel D. This wheel ispreferably made much wider than those generally used for the purpose ofpreventing it sinking into the loosened clay.

E is an iron frame passing over the scoop and connecting the trunnions,as shown.

E is a hardwood girder, which may be secured to the top of frame E forthe purpose of lending additional strength and rigidity thereto.

B is the cross-bar of the frame.

F isa post, the lower end of which is secured to the center of cross-barB, the top being connected by the bar G to the top of frame E.

H is alever pivoted at H to top of the frame E. The forward end of thislever is confined in a slot cut in the center post F. The lever isoperated by screw J by means of the spurgearing K, hereinafterdescribed. The screw J passes through and is supported by a bracket J onthe bar G. In the lever H a nut h is fitted, through which the screw Jpasses and with which said screw engages, as shown in Fig. 5, and thenut has trunnio'ns h, whereby the lever may move on its fulcrum inresponse to the turning of screw J.

L is a vertical controlling-arm pivoted to the forward portion of thelever H and extending therefrom into contact with the center of thecutting edge of the scoop. M is a corresponding arm pivoted to therearward end of the lever H and extending into contact with the top edgeof the back of the scoop. This arm is provided with a foot M to allowfor any play in the parts.

' N is a. door, and N is a frame carrying same, pivoted at B B N is afoot-lever, by means of which the door is opened and closed.

P is a frame carrying drivers seat P and to which the lever N ispivoted.

Q is a governing-rod pi voted to lever-arm M.

R is a spring, and S a retaining-bar provided for the purpose ofcontrolling the movement of the pivoted lever-arm L, as hereinafterdescribed.

The method of operating my invention is as follows: In Fig. 2 the scoopis shown with its cutting edge raised from contact with the ground andwith the door closed-that is to say, in the position the scoop wouldtake during transit. To put it into position for filling, the driversitting on his seat rotates the gear-wheel K by means of the handle K,thus depressing the forward end of the lever H and causing the arm L toin turn depress the cutting edge of the scoop until it arrives at theposition for filling, as shown in Fig. 1. At the same time the driverdepressing the forward, end of the foot-lever N lifts the door clearaway from proximity with the cutting edge of the scoop into positionshown in Fig. 1. The team is then driven forward and the scoop filled,the forward and rearward leverarms L and M retaining the scoop firmly inposition meanwhile. When the scoop is full, the driver rotates thegear-wheel K in the reverse direction, thus depressing the rearward armM and with it the back portion of the scoop, which movement of courseraises the cutting edge from contact with the ground. He also releasesthe foot-lever, thus allowing the door to drop till the stud N rests onthe frame B-that is, till the lower edge of the door meets the cuttingedges of the scoop. The parts have now resumed the position for transit,as shown in Fig. 2. The scoop is then drawn to the place where it isdesired to unload. Inorder to bring it into position for this purpose,the door is again raised, the cutting edge forced into contact with theground, and rearward lever-arm thrown out of gear by the bar Q beingshoved backward, as shown in Fig. 3. The forward movement of the teamcontinuing the cutting edge catching in the ground causes the scoopto-tumble, and thus throw out its load. As during this movement the.back of the scoop will come into contact with the forward leverarm L thelatter is pivoted at L, so that it does not obstruct the rotation of thescoop. The spring R is provided to draw the arm back to its originalposition against the stop S on the bar S. During the time this movementis taking place the driver adjusts his lever to the position shown inFig. 2, thus putting the parts once more into the position for transit.The scoop is so constructed that when empty, the rearward portion beingthe heavier, the cutting edge will always rise clear of the ground whennot depressed by the lever.

It will be seen that the distance between the axis of the scoop and thefront cutting edge is greater than the height of the axis of the scoop.

,its ends, and members pendent from the lever and adapted to bearrespectively on the front and rear of the scoop? 3. The combination witha wheeled frame of an earth-scoop mounted to have a complete rotarymovement in the frame, the distance between the axis of the scoop andits front edge being greater than the height of the axis of the wheelsfrom the ground, so that the front edge may be caused to so enter theground as to overturn the scoop.

4. The combination with frame, of a scoop mounted to turn, a lever abovethe scoop, a pivoted member pendent from the lever to bear on the rearend of the scoop, and a rod for moving the said pivoted member out ofthe path of movement of the scoop,

5 The combination with a frame, of a scoop mounted to turn completelyover, a

pivot-ed member pendent in the frame and normally bearing on the frontof the scoop, and a spring exerting a rearward tension on the pendentmember,

' In witness whereof I have hereunto set my l hand at Sydney, New SouthWales, this 12th day of April, 1900,- in the presence of two wit- 1nesses. wheels, so that the front edge may be caused 1 to dig into theground in such a manner that t the forward movement will overturn the\VILLIAM MATTHEWS.
